SS Template Editor suggestions

Hi folks, as kind of learning project I'm planning to code a kind of Template/Theme Editor in QT and don't really know which features would be useful. First of all I though about drag&drop support for just dragging some items out of a list (wysiwyg style) and then u can export it into an ss file and automatic folder structure. It would be nice if some of you could make some suggestions for the editor and its features and I will see what can be done and makes most sense too me.

Because I'm quite a novize to QT and also SS I cant say how long it will take to get a working version ready for download but I'm looking forward to get it done asap.
